Abstract

The present application relates to the technical field of dust jackets, and specifically discloses a TPE dust jacket for preventing abnormal noise, which is characterized by comprising the following components: TPE; solid paraffin; reinforcing agent; and other auxiliary agents. A production process of a TPE dust jacket for preventing abnormal noise, comprising the following steps: S1, heating and melting TPE, adding solid paraffin, stirring and mixing evenly, to obtain a mixture A; S2, dividing the white oil into a first part of white oil and a second part of white oil. Two parts of white oil, adding flexible coke powder and the first part of white oil to mixture A, and stirring evenly to obtain mixture B; S3, adding the second part of white oil to the aqueous solution of starch, and then adding water-in-oil emulsification The emulsion is made into an emulsion, and the emulsion and carbon black powder are added to the mixture B to obtain the mixture C; S4, other additives are added to the mixture C, stirred and mixed evenly, and the elastomer particles are obtained through granulation; S5, the elastic The granules are injection-molded, blow-molded, and cut to obtain a dust jacket. By adding solid paraffin, the dust jacket is less prone to abnormal noise.

Description

technical field [0001] The present application relates to the field of dust jackets, and more particularly, to a TPE dust jacket with anti-abnormal noise and a production process thereof. Background technique [0002] The dust cover is located around the car ball cage. It is the ball cage cover of the car drive system. It is used to store grease and prevent dust, sand, water, salt, etc. from entering the lubrication system. The dust cover is one of the important parts of the car. , the dust cover needs to be able to withstand the extremely abrasive operating conditions created by the mud and dirt on the road, and also needs to maintain a high degree of flexibility in extreme temperature conditions to accommodate the sharp corners that the car may take. [0003] The dust cover is usually made of TPE material. TPE material has high rubber strength and high resilience, and has the characteristics of injection molding. It is also environmentally friendly, non-toxic and safe, wit...
